Will I ever be able to trust my wife again?

As long as your kids are grown, it’s safe to divorce. I’m assuming they are all out of the house?

The only advice I give in situations like this is to follow your happiness. Consider your options that you may have forgotten. A friend of mine and his wife divorced after 29 years of marraige. They lived in the suburbs of a rather boring town that she wanted to live in, they had a stale life, basically. He always wanted to live in a big city and enjoy different foods and nightlife and walk through crowded streets. he moved to New York city and is a different man, to say the least! He has what he wanted out of life and is happy, when hedidn’t even want the divorce–she did. Now she’s still living a stale and lonely life and he’s out taking dance lessons and having a blast making new friends and going to art galleries and concerts in New York.

Now that your wife has decided there was a better life out there somewhere, I think you would be justified at this point to decide whether there is a better life out there for you, too. If there is, I’m not saying divorce and go for it, just consider it, the way she considered leaving you. If you want to be with her, do that.
